A shaft is required for a chain drive illustrated in figure 5.42.  The power transmitted is 12 kW at 100 rpm. The masses of the sprockets are 5 and 16.3kg, with respective diameters of 254.6 and 460.8 mm. The material selected for the shaft is quenched and drawn 817M40 with ultimate tensile strength 850 MPa and yield strength of 700 MPa. The torque is transmitted between the shaft and sprockets by means of keys in profiled keyways. Determine the minimum diameter for the shaft based on the ASME equation for the design of transmission shafting if the desired reliability is 90 per cent. Use an initial estimate for the shaft diameter of 60 mm.
